llvm-6502/lib/Target/ARM/ARMScheduleA9.td
Andrew Trick 6c9712fecb New machine model for cortex-a9. Schedule for resources and latency. 
Schedule more conservatively to account for stalls on floating point
resources and latency. Use the AGU resource to model latency stalls
since it's shared between FP and LD/ST instructions. This might not be
completely accurate but should work well in practice.
